O objetivo deste trabalho foi hierarquizar alternativas de macrodrenagem urbana na Sub-bacia 2 da Bacia Hidrográfica da Estrada Nova (BHEN) em Belém-PA, Amazônia, Brasil, para auxílio na seleção de alternativa a ser implantada. A metodologia utilizada considerou critérios técnicos, ambientais e econômicos, e foi aplicada a cinco alternativas possíveis para a funcionalidade da Sub-bacia em estudo, as quais foram desenvolvidas com o uso do código computacional livre Storm Water Management Model (SWMM). Na modelagem considerou-se precipitação de 50 anos de retorno, marés, comprimentos, seções dos canais, galerias e pontes existentes, coeficientes de Manning de revestimentos, disponibilidade de áreas para implantação de componentes necessários à funcionalidade do sistema, como novos canais, unidades de armazenamento e comportas. Dentre as cinco alternativas a segunda foi a mais bem classificada, essa considera concordância de seções e unidade de armazenamento. Desta forma, os resultados obtidos foram muito promissores e confirmaram a expectativa pelo uso de melhores práticas de manejo de águas pluviais, tendo a metodologia utilizada permitido a resolução do problema muito satisfatoriamente.

Drainage Channels

Tarakan City experiences problems with standing water during the rainy season, especially in the west Tarakan sub-district which is the center of Tarakan. This puddle not only submerged settlements and offices but also shops and access roads that caused considerable economic losses. An evaluation was carried out by using the Storm Water Management Model (SWMM). SWMM is a rainfall-runoff simulation model used for simulating the quantity and quality of surface runoff from urban areas. Based on the evaluation using SWMM software, the drainage system in Tarakan, especially in Jalan Mulwarman has several inundated channels, namely channels 2, 3, 4, 5, 6, 7, 11, 12, 13, 14. This is influenced by the dimensions of the drainage channel that cannot accommodate existing water runoff and sediment thickness that covers the drainage channels so that the capacity is reduced, if it rains it will cause puddles at several points in Tarakan City. In order to deal with these puddles, it is necessary to change the dimensions of the channel and routinely dredge sediments that cover the drainage channels.

Sewer Overflow

AbstractThe objective of the present study to assess the performance of a suggested sewer line by using pipe jacking system (PJS) in order to enhance the sewage capacity and mitigate sewer flooding of historic pilgrimage city of Karbala, Iraq. The storm water management model (SWMM5) was used for this purpose. The simulation of exiting sewer system reveals that sewer discharge during peak pilgrimage period is more than 200% of the capacity of existing sewer line. Installation of SLL having a diameter of 2.5 m at a depth ranging between 12 and 22 m by PJS can reduce water depth in sewer pipe by 78%. The reduction of water depth at sewer pipe can reduce sewer overflow up to 70%, if the system is installed and managed properly. The methodology proposed in the paper can be applied in any location having similar problem with necessary modifications.

Abstract The verification of simulation model of combined sewage system was presented in article. The model of sewage system functioning in Głogów was developed using SWMM 5.1 (Storm Water Management Model) software. It was calibrated based on the results of field studies from the years 2011–13, while the properness of its activity was verified for the results of measurements carried out in 2014. The verification of the model showed acceptable discrepancies between the measured and simulated values of flow rates. Factors which caused differences were indicated and, on the basis of this, conclusions pertaining to further studies were formulated.
